JAMES FARMER, OF SALFORD, ENGLAND.

MACHINE FOR PRINTING OR EMBOSSING FABRICS.

SPECIFICATION forming part of Letters Patent No. 477,205, dated June 21,1892.

Application filed September 16, 1889. Serial No. 324,166. (Modeh)Patented in England January 12, 1889, No. 603.

To all whom it may concern:

Be it known that 1, Sir JAMEs FARMER, a subject of the Queen of GreatBritain, residing at Salford, in the county of Lancaster, England, haveinvented certain new and useful Improvements in Machinery for Printingor Embossing certain Fabrics and Materials, (for which I have obtainedLetters Patent in Great Britain bearing date January 12, 1889, N0. 603,)of which the following is a specification.

My presentinvention consists in certain improvements on the inventionfor which I obtained Letters Patent in the United States, No. 408,913,dated August 13, 1889, and in Great Britain, numbered 10,431, dated July27, 1887, and entitled improvements in and machinery for printingfloor-cloths and textile and other fabrics and materials and also forembossing certain materials or fabrics.

The objects of my present improvements are to improve the mechanism foractuating the printing-blocks and the arrangement for inking the same. Iattain these objects by the mechanism illustrated by the accompanyingsheets of drawings, in which- Figures 1 andl represent a side elevation,Figs. 2 and 2 a plan, and Fig. 3 an end elevation, of a two-eolorprinting-machine-that is, a printing machine provided with two separatecolor-boxes and printing-blocks, each box having a different color-towhich my improvements have been applied. Fig. 4 shows the inking-rollerappliance. Fig. 5 is a longitudinal section of a two-color machine, allunnecessary parts omitted. Figs. 6 and 7 show the printing-b1ocks (Z atdifferent times in the forward stroke, as indicated by the arrows. Fig.8 shows the blocks (6 on their return stroke when they are supported andtravel back upon the lever g above the inclined rails e and clear of theinking-roller. Figs. 9 and 10 represent side and end views of one of theprinting-blocks (Z. Figs. 11 and 12 represent the inking-rollerj and thecolorbox t', with the screws by which it can be adj usted vertically.

Referring to the drawings, a designates the main frame of the machine.

I) I) are two frames mounted in slideways a (see Fig. 3) on the frame aand coupled together adj ustably by screwed co nnecting-rods c and nuts0' or equivalent connections, so that the distance apart of the twoframes I) can be regulated as required. To these combined framesb asliding reciprocating movement to and fro on the main frame a isimparted by the mechanism shown and heroinafter described or by anyother suitable and convenientarrangement. Each of the sliding frames Z1has a standard I)", in whichis a slideway titted with a slide-block band each pair of slide-blocks b on opposite sides of the machine earryone of the printing-blocksd. On a shaft extending across the machine oron a trunnion b secured to or formed with each sliding block is mountedan anti-friction roller b, which runs on a guide-rail c, fixed 0n themain frame a. These guide-rails e for a certain length beyond each blockcl lie in a horizontal plane and then dip down and rise again in a curveto a horizontal plane, as shown best in Fig. 1. Below the bottom of eachdip or curve in the guide-rails e is placed a sliding table f, to whicha reciprocating motion is imparted at a certain time as and by the meanshereinafter described. To a bracket a on the framing and above thecenter of each dip in the guide-rails e are pivoted an elbow-lever g onthe side nearest the first block (Z and a short lever 71. on the otherside. The long arm of each lever g is kept normally raised, as shown inFig. 1, by means of a weight g or by a spring, while each short lever his kept by its own weight normally lowered in a horizontal orapproximately-horizontal plane. Between each printingblock d and dip inthe guide-rail is placed a color-box 'L', which is vertically adjustableby means of screws 1', and in each color-box is mounted a color-rollerjand a doctor-roller 7r. On each color-roll'erj is fixed a pinion j,gearing into a pinion It on the doctor-roller 7e and on each forwardstroke of the sliding frames 1), while the rollers l) are running on theguide-rails c, racks (Z, fixed on the under side of the printing-blocks(Z, gear into the pinions j, and so drive both the colorrollers j anddoctor-rollers 7.;. On the return stroke of the sliding frames 1), whilethe rollers Z)" are running on the upper side of the elbow-levers g, assubsequently explained, the racks (1 pass over without drivingthepinionsj, so that the color-rollersj and doctor-rollers 7; remainstationary until the next forward stroke of the sliding frames 1).

The mechanism for imparting a reciprocating movement to the slidingframes Z) in the arrangement shown consists of the following parts: Thedriving-shaftl carries a pinion Z, which gears into and drives aspur-wheel m, fixed on a shaft 171, on which is also fixed a :0 disk mwith an eccentric-pin m connected by a link a to one of two rockinglevers 0, which are fulcrumed and fixed on a rocking a shaft 0',supported in bearings a in standards I The upper ends of the rockinglevers 0 are connected by links 0 to the of the frame a.

sliding frames 1), so that as the disk m revolves and the eccentric-pinm thereon by the link n rocks the levers 0 a reciprocating motion isimparted by the links 0 to the slid 2 5 ward the pairs of stops b I)come in contact with and carry forward for a certain distance thesliding tables f, while on the return stroke the sliding tables f aremoved backward by the pairs of stops 1) b 0 The floor cloth or fabric 1)to be printed is batched upon a roller 19, supported in stand ards p andthe fabric is traversed through to insure good printing, preferably bymeans 3 5 of a traveling chain r on either side of the These chains r,which have needle-points, extend from end to end of the maj chine, andaremounted upon chain-wheels 0*,

machine.

which are supported on the framing a. The

a guide or roller 19 which extends across the width of the machine, andis pressed onto the needle-points of the chains 9' at each edge by meansof brushes 5, which are fixed one above each of the first pair ofchain-wheels r. The

'second pair of chain-wheels *r are fixed upon a shaft r upon which isalso fixed a bevelgear r which is driven by a bevel-gear t, fixed upon ashaft 2?. On the other end of this shaft 25 is'fixed a bevel-gear 15which is driven by a bevel-gear u on a shaft to, on which is also fixedadj ustably an elliptical gear M, which is driven by another ellipticalgear '0, fixed on a shaft r.

spur-wheel m fixed on the shaft m, which receives motion from thedriving-shaft a, as before described. As the chains 1" and chainwheels7' are driven from the shaft m, which can insure the fabric 19 travelingat the exact speed required at the moment of printing.

The operation of the machine is as follows:

The shafts-also has fixed 55 upon it a spur-Wheel 19, which is driven bya J As the rocking levers 0 oscillate and the combined sliding frames 1)I) begin to move forward, each printing-block cl passes over and isinked by its color-rollerj, which is caused to rotate while theprinting-block passes over it by means of the rack (1 and gears, asdescribed. After the printing-blocks (1 leave their respectivecolor-rollersj they pass under the raised long arms of the pivotedelbowlevers g, and leaving the horizontal portions of the guide-railscthey descend the curves and print the fabric 1) upon the sliding tablesf, which at that moment are caused to move forward with the slidingframes 1) by means of the pairs of stops b b, as before described. Thefabric also being drawn forward by the chains 7'', which at the momentof printing are driven at exactly the same speed as that at which theprinting-blocks d are mo-ving,it follows that the printing-blocks (Z,the fabric p, and the sliding tables f all travel forward together atexactly the same speed. Immediately thefabric has been printed theprinting-blocks d begin to leave the sliding tables f as they ascend theopposite sides of the curves in the rails c, and then rising and passingunder the second pairs of pivoted levers 71. they again arrive onhorizontal portions of the guide-rails e, but

.; on the opposite side of the curves from that on which they started,the letters It falling down again after the rollers bi have passed.

The rocking leverso now begin to move in the the machine at the varyingspeeds necessary reverse direction, and as the sliding frames 1), withthe printing-blocks 61, return the rollers b run on the upper side ofthe pairs of pivoted levers h and g, the levers gbeing pressed down intothe required position by the rollers 19 passing over them. During thegreater portion of the return movement of the sliding o fabric 1) passesfrom the batch-roller 1) over frames 1) the sliding tables f remainstationary; but a little before the rollers 19 leave the levers g andcome again onto the surface of the guide-rails e the stops 6 b catch thetables f and push them back to their initial positions, ready for thenext printing stroke.

Although for convenience of description I have specified my invention asapplied to a two-color printing-machine,itis obvious that myimprovements are equally applicable to a single-color printing orembossing machine and also to machines with three or moreprinting-blocks. I

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim, and desire to secure by Letters Patent of the UnitedStates, 1s
